variable name and array

[rickw]

Hi,

I am working with sas arrays I want to output a value and variable name and value in one column that has a value greater than say 10.

I am running sas code similar to this :

data temp; set temp2;

array abs{*} _numeric_;

do i = 1 to dim(abs);
if(abs(i) > 10) then variable_gr10 = x1|| ... here i want to append name of the variable
end;

run;

Is there any way I could simply get name of the particular variable and append it with another value in the data ?

Thanks

Just wondering...
http://support.sas.com/documentation/cdl/en/lrdict/63026/HTML/default/viewer.htm#a000201956.htm

are you seeing any warning messages in the SAS log. ABS is the name of a SAS function.
doc for ABS function:

It says in the doc:

CAUTION:
Using the name of a SAS function as an array name can cause unpredictable results.

If you inadvertently use a function name as the name of the array, SAS treats parenthetical references that involve the name as array references, not function references, for the duration of the DATA step. A warning message is written to the SAS log.


As for your question about creating a new character variable, then this code shows how to use the VNAME function to grab the variable name of an array member.
